The effect of spherical aberration on temperature distribution inside glass by irradiation of a high repetition rate femtosecond pulse laser
In this paper,we study the effect of spherical aberrations on the light intensity and the temperature distribution in the focal region in a 250-kHz femtosecond laser irradiated Ag +-doped borosilicate glass.When a focused beam goes through an interface between air and glass,spherical aberration will result in the separation of the focal point and then cause a clear change of the light intensity distribution along the incident direction.That phenomenon will further influence the longitudinal cross-section temperature distribution in glass.Here we use Ag nanoparticle formation as a marker for establishing temperature distribution and we find that the formation of nanoparticle shows a strong dependence on the temperature field and the detailed precipitation process is also discussed.
